IMPROVEMENT IN BEARINGS FOR UPRIGHT SHAFTING.

Specification forming part of Letters Patent No. 169.864, dated November9, 1875; application filed October 21, 1875.

To all whom it may concern:

Be it known that I, JOHN H. TEAHL, of Reading, in the county of Berksand in the State of Pennsylvania, have invented certain new and usefulImprovements in Bearings for Upright Shafting and do hereby declarethatthe following is a full, clear, and exact description thereoflreferencebeing had to the accompanying drawings and to the letters of referencemarked thereon, making a part of this specification. The nature of myinvention consists. in the construction and arrangement of a bushing orhearing for mill-spindles, upright shafts, &c., as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a plan view of my invention, with the lid or cover of thereceiver removed. Fig. 2 is a vertical section taken through the line 50a: of Fig. 1. Fig. 3 is a plan view of the cover. Fig. 4 is a bottomview of a washer used with the cover.

A represents a. receiver of any suitable dimensions, and of any desiredexterior form. The interior of the receiver is made in funnel shape, asshown in Fig. 2. B represents the upright mill spindle or shaft, whichpasses up through the center of the receiver A, and has receiver. Thetop and bottom of this cage is provided with five radial arms, a a, atequal distances apart, which arms areslotted from the outer ends inward,for a suitable distance. The arms 'at the top and bottom correspond witheach other, so as to form pairs for the reception of five taperedrollers, D D, the journals of which have their bearings in boxes Ir b,placed and sliding in the slotted arms a a,

of the cage 0. The rollers D D are tapered so as'to engage with theinside tapering surface of the receiver, and on the inner side, therollers engage with the spindle B, making the bushing anti-friction andself-tightening, the spindle serving as a guide for the cage or skeletonO. The arms with the sliding boxes keep the rollers perpendicular withthe spindle, at the same time allowing them to find the center betweenthe receiver and the spindle, keeping the spindle in the center of thereceiver.

The lid or cover E, for closing the top of the receiver is formed withnotches w in its edge. It rests upon an annular shoulder, y, and isturned under lips or flanges z, to be held in place. Above the lid E isa washer, G, fitting over the flange or rim (1 on the lid, and restingon a shoulder, e, of the spindle, to keep the bushing from leaking, andallow the air to pass up through the bush in the burrs. The spindle may,if desired, be made tapered in the same proportion as the receiver androllers.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of the funnel-shaped receiver A, cage (J, withslotted armsA, having sliding boxes b, and the tapering rollers D, withthe spindle B, substantially as and for the purposes set forth.

2. The lid or cover E, having notches m, and top flange cl, incombination with the receiver A, having shoulder y, and flanges z, andthe washer G, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this19th day of October, 1875.

JNO. TEAHL.
